Biography & Historical Record
Liu Yan (Wei) (刘延, Lưu Diên) (dates unknown) was Administrator of Dong Commandery (东郡, Đông Quận) under Cao Cao (曹操, Tào Tháo) during the late Eastern Han. Stationed on the Yellow River frontier at Baima (白马, Bạch Mã), he held the northern gate of Cao Cao’s base while Yuan Shao (袁绍, Viên Thiệu) pressed south. He is not the Yi Province warlord Liu Yan (刘焉, Lưu Yên) (id 3838 /liu-yan/) — different hanzi, era role, and slug liu-yan-wei.
In 200 AD Yuan Shao’s vanguard under Yan Liang (颜良, Nhan Lương) besieged Baima. Liu Yan held the walls and sent urgent appeals to Xuchang. Cao Cao marched to relieve him; Guan Yu (关羽, Quan Vũ) rode into Yan Liang’s ranks, took his head, and broke the siege — a pivotal early stroke of the Guandu campaign. Historically the stand at Baima bought Cao Cao the time to counterattack; literarily it frames Guan Yu’s first great exploit in Cao Cao’s service.
Role in Romance of the Three Kingdoms
Chapter 25 (Besieged in Tushan, Guan Yu Makes Three Conditions; Relieved at Baima, Cao Cao Breaks the Siege): Yan Liang’s host surrounds Baima. Wei officers Song Xian (宋宪, Tống Hiến) and Wei Xu (魏续, Ngụy Tục) fall or fail in combat; Xu Huang (徐晃, Từ Hoảng) cannot turn the tide. Liu Yan watches Guan Yu gallop down, spear through the enemy front, and return with Yan Liang’s head — lifting the siege that had nearly crushed Dong Commandery.
Chapter 27 (The Beautiful Beard Rides Alone a Thousand Li; Guan Yu Slays Six Generals Across Five Passes): Escorting Lady Gan (甘夫人, Cam Phu Nhân) and Lady Mi (糜夫人, My Phu Nhân) toward Liu Bei (刘备, Lưu Bị), Guan Yu reaches Dong Commandery. Liu Yan greets him with honour for the Baima debt, yet refuses a ferry across the Yellow River: the crossing is guarded by Qin Qi (秦琪, Tần Kỳ) under Xiahou Dun (夏侯惇, Hạ Hầu Đôn), and Cao Cao’s permit law forbids private passage. Reminding Liu Yan of Yan Liang’s head brings only an apology — fear of law, not ingratitude. Guan Yu proceeds to the ferry and slays Qin Qi himself.

Homonym caution: do not confuse with Liu Yan (刘焉, Lưu Yên) of Yi Province.
Key Relationships
Family
- No father, mother, spouse, or children are named in Sanguozhi notices of the Baima defense or in the novel chapters that feature him — treat kin as unattested.
Friends
- Cao Cao (曹操, Tào Tháo): Lord and Chancellor; Liu Yan holds Dongjun / Baima as his frontier administrator.
- Guan Yu (关羽, Quan Vũ): Novel: saviour at Baima (Ch. 25) and later guest whom Liu Yan dare not ferry (Ch. 27). History: Guan Yu’s killing of Yan Liang in Cao Cao’s service is the attested stroke that relieved the northern pressure.
- Xu Huang (徐晃, Từ Hoảng), Song Xian (宋宪, Tống Hiến), Wei Xu (魏续, Ngụy Tục): Fellow officers in the Baima fighting before Guan Yu’s charge (novel colour for Song/Wei; Xu Huang also historical Wei general).
Enemies
- Yan Liang (颜良, Nhan Lương): Yuan Shao’s grand general who besieges Liu Yan at Baima until Guan Yu takes his head.
- Yuan Shao (袁绍, Viên Thiệu): Northern warlord whose Guandu offensive places Baima under siege.
Other
- Xiahou Dun (夏侯惇, Hạ Hầu Đôn): Senior Cao commander whose ferry regulations Liu Yan cites when refusing Guan Yu a boat (Ch. 27).
- Qin Qi (秦琪, Tần Kỳ): Officer at the Yellow River crossing under Xiahou Dun; Guan Yu slays him after Liu Yan’s refusal.
- Homonym — Liu Yan of Yi (刘焉): Separate post at /liu-yan/; never merge family or links with 刘延 of Dongjun.
In Novel
Chapter 25
- Liu Yan (Wei) (刘延, Lưu Diên): Administrator of Dong Commandery holding Baima against Yan Liang (颜良, Nhan Lương). After Song Xian, Wei Xu, and Xu Huang fail to stop the Yuan vanguard, he witnesses Guan Yu (关羽, Quan Vũ) ride into the enemy lines, take Yan Liang’s head, and lift the siege for Cao Cao (曹操, Tào Tháo).
Chapter 27
- Liu Yan (Wei) (刘延, Lưu Diên): Greets Guan Yu with honour for the Baima debt while escorting Lady Gan and Lady Mi, yet refuses a Yellow River ferry because Qin Qi under Xiahou Dun enforces Cao Cao’s permit law. Apologizes that fear of law, not ingratitude, stays his hand; Guan Yu then forces the crossing by slaying Qin Qi.
In History
Summary
- Liu Yan (刘延, Lưu Diên) appears in the Guandu narrative as Cao Cao’s Administrator of Dong Commandery at Baima. When Yan Liang attacked, Cao Cao’s relief — and Guan Yu’s killing of Yan Liang — broke the siege. Later Five Passes colour is largely novelistic.
Year: 200 AD
- Baima besieged by Yuan Shao’s forces under Yan Liang; Cao Cao marches to relieve Liu Yan; Guan Yu kills Yan Liang in the field — a key early Guandu success.
Historical Record
- Sanguozhi (Wei) campaign notices for Guandu / Baima; Guan Yu’s biography for the slaying of Yan Liang. The Dongjun ferry refusal of Chapter 27 is Romance elaboration, not a separate SGZ biography for Liu Yan.
